FIG. 1 in Dead Spadefoot Tadpoles Adaptively Modify Development in Future Generations: A Novel Form of Nongenetic Inheritance?

FIG. 1. Study system. Mexican Spadefoots, Spea multiplicata, breed in (A) ephemeral pools that (B) dry rapidly (this is the same pond as in panel 'A,' but nine days later). (C) Consequently, the tadpoles often desiccate before reaching metamorphosis. (D) To speed development, Spea tadpoles have evolved phenotypic plasticity to shift from an 'omnivore' morph (left) to a more rapidly developing 'carnivore' morph (right).
